Here's what Jim Cramer had to say Wednesday night about some of the stocks during the Mad Money Lightning Round:

Berkshire Hathaway (BRK.B) - Get Report : "I'd buy more. That stock is incredibly undervalued."

Westar Energy (WR) : "I prefer Dominion Resources (D) - Get Report and American Electric Power (AEP) - Get Report ."

Wisconsin Energy (WEC) - Get Report : "I say stick with it and buy some on weakness."

SAP AG (SAP) - Get Report : "I think SAP is doing well and I'd be a buyer. I'd buy Accenture (ACN) - Get Report too."

Mettler-Toledo International (MTD) - Get Report : "It's a little overvalued, but I don't mind buying on weakness."

Halyard Health (HYH) : "I cannot recommend you buy this one."

McDermott International (MDR) - Get Report : "I think this infrastructure play is a good one."

Freeport-McMoRan (FCX) - Get Report : "I think they've done a lot of the balance sheet work they needed to do and can now go higher."
